Back Door

A route through which legitimate users or criminals can bypass security systems in order to access the data they’re after. Contrasts with a front door attack, where a virus or attack is done with help from the user, for instance by downloading an infected email attachment.


Baiting describes the situation where a fraudster leaves something out like a USB drive, enticing somebody to pick it up and see what content is on it. The fraudster loads the USB drive up with things like malware and keyloggers, which attack a computer system when plugged in. This scheme is designed to take advantage of people’s curiosity.

Bank Identification Number (BIN Number)

A BIN Number or Bank Identification Number is assigned to a bank for its own credit card issuance.

The first six digits on a credit card constitute the Bank Identification Number, otherwise known as the BIN number. A BIN identifies the institution that issues the credit or debit card. The American Bankers Association manages the ISO Register of BINs and Issuer Identification Numbers(IINs) for US banks. Online merchants use BINs (Bank Identification Numbers) as an extra measure to confirm the geographic area where the cardholder is located. For instance, they compare it to the geographic area identified by the unique BIN number. Occasionally, some refer to BIN Numbers as an IIN or Issuer Identification Number.

BIN Attack Fraud

One way fraudsters use BIN numbers is in scams known as BIN Attack Fraud. The fraudster obtains a BIN and uses software to generate the remaining numbers. They then test the numbers using small transactions through online retailers until they find a valid and active card number. 

Common signs of a BIN attack:

  • Multiple low-value transactions that are unusual for your business
  • Multiple declines
  • Unusually high volumes of international cards
  • Large quantity of transactions being processed or attempted in a short period of time
  • Card numbers being used repeatedly with variations in the security features
  • Unusual transaction times

    Burn(er) Phone

    The term originates from the drug dealing world, and is used to describe inexpensive mobile phones designed for temporary use. It allows fraudsters and criminals to link an account to a disposable phone number, for instance to bypass 2FA.

    Today, phone numbers can be generated via burner phone apps or services. These work like prepaid phone cards, only allowing you to use them for a limited amount of time before being recirculated. Because they go through your phone’s original cellular data, they can be traced.
